Add support for BeTrue and BeFalse assertions
Added interface to allow different printing styles.

This change is a no-op for existing goblin users.  This is only
useful if you are running in a terminal that doesn't understand
the ansi color codes. This matters to users of go sublime because
sublime isnt a terminal so the colors and check make the output

Added support for detecting a tty.
Remove terminal dependency and fix indentation issues
Add timeout support
Update readme
